Abstract To improve the corrosion resistance of Cu to GaIn alloy, Cr coating and Al coating were sputtered on the surface of pure copper by multi-arc ion plating.Cr/Cr₂O₃/Al₂O₃ composite coating, Cr/CrN/SiO₂ composite coating and Al/Al₂O₃ /Al₂O₃ composite coating were prepared by in-situ reaction and sol-gel method. Corrosion tests were carried out in GaIn alloy at 60 ℃ and 200 ℃.GaIn alloy can cause severe pitting corrosion on the surface of copper block, but during the corrosion process, copper-gallium intermetallic compound which is attached to the surface of copper block will reduce the corrosion rate of GaIn alloy to copper block.GaIn alloy can cause serious corrosion to Al/Al₂O₃/Al₂O₃ coating.Large area of coating was desquamated. Cr/CrN/SiO₂ coating was relatively stable in GaIn alloy, but the outermost layer of SiO₂ showed a large amount of chipping. Cr/Cr₂O₃/Al₂O₃ coating was not obviously corroded in GaIn alloy. With the increase of corrosion temperature, the corrosion rate of GaIn alloy to samples also increased.The corrosion rate of copper at 200 ℃ was significantly more than 269 times that at 60 ℃, and the corrosion products adhering to the surface of copper were mainly CuGa₂. Cr/Cr₂O₃/Al₂O₃ coating has the best corrosion resistance to GaIn alloy.Corrosion rate of Cr/Cr₂O₃/Al₂O₃ coating in GaIn alloy at 200 ℃ was 0.049 5 μm/h.The effect of Cr/Cr₂O₃/Al₂O₃ coating on thermal conductivity is around 1%.
